How Brecknockshire compares
Brecknockshire ranks 51st of the 85 counties we track for solar yield. Self use does the heavy lifting here: of the £829 year one benefit on a typical 12 panel system, £247 comes from replacing 26.32p imports with your own generation, which is why battery sizing matters more than panel count.
Treat these as calibration rather than a quote. The calculator below opens on Brecknockshire's own PVGIS yield and prices a 12 panel system at £6,360 installed before any battery; your free design call reworks every number for your roof.
The charger is in the installed price but left out of payback: charging savings depend on your mileage and tariff, which the design call models properly.

The network operator for Brecknockshire
On NESO's licence-area map, the middle of Brecknockshire falls in South Wales, which National Grid Electricity Distribution (NGED) operates, and so do all the towns we cover in the county.
What decides the paperwork is the inverter and battery output, not the number of panels. Up to 3.68kW per phase, a system follows G98: NGED is notified within 28 days of commissioning and nothing has to be approved first.
Larger systems go through G99 instead, applied for before installation. On timing: NGED's guaranteed standards give 45 working days for a low voltage generation quotation, with £80 paid for each working day late.

Heat pumps and EV charging in Brecknockshire
A heat pump in Brecknockshire
In December, the darkest month here, 12 panels in Brecknockshire make about 170 kWh. That is when a heat pump runs hardest, so its running cost in Brecknockshire comes down to the tariff and the flow temperature rather than the roof.
Grant support in Wales comes from the Boiler Upgrade Scheme: £7,500 for an air source or ground source heat pump, £2,500 for air-to-air, and an extra £1,500 until March 2027 where the home is heated by oil or LPG off the gas grid (gov.uk, checked 28 September 2026).
Charging an EV in Brecknockshire
Summer is where a car earns its place. In May, 12 panels in Brecknockshire make about 750 kWh, against roughly 70 kWh a typical home uses in daylight that month on our calculator's typical-use settings, so there is surplus a smart charger can put into the car instead of exporting it.
The calculator above includes a 7.4kW smart charger from £1,100 installed. Renters and flat owners with off-street parking can claim 75% of a chargepoint's cost, up to £500 per socket, until 31 March 2027 (gov.uk, checked 28 September 2026).

Solar in Brecknockshire: your questions answered
How much energy would 12 solar panels make in Brecknockshire?
Brecknockshire averages 2.50 peak sun hours a day, which PVGIS turns into 911 kWh per kWp a year. On a 12-panel, 6.36 kWp roof that is about 5,790 kWh, 70% of it between April and September.
What does a typical solar system cost in Brecknockshire?
Solar is priced at £1,000 per kWp installed wherever you live, so a 12-panel, 6.36 kWp system costs £6,360 in Brecknockshire, exactly as it would anywhere else, before any battery. Location changes what the system makes, not what it costs: here that is about 5,790 kWh a year. The final figure comes from your roof on the design call.
Who is the network operator in Brecknockshire, and do I need a G99 application?
The operator is National Grid Electricity Distribution (NGED). Most home systems use the G98 route, a notification within 28 days of switch-on for up to 3.68kW per phase, so nothing waits on the network. Above that, G99 applies and has to be granted first. NGED's guaranteed standards give 45 working days for a low voltage generation quotation, with £80 paid for each working day late. Your design call checks which route yours needs.
What happens to the solar I do not use in Brecknockshire?
Around £583 a year at 12p per kWh, for the roughly 4,857 kWh a 12-panel system in Brecknockshire exports with typical use. Rates vary by supplier and some need their own tariff; the export rates table is dated and sourced.
How does solar perform in Brecknockshire in the winter months?
December is the weakest month in Brecknockshire: about 170 kWh from 12 panels, against 750 kWh in May. The panels still generate on bright winter days; they just cover a smaller share of what the house uses.
